Specification of Letters Patent.

Application filed May 4, 1907. Serial No. 371,948.

To all whom it may concern:

Be it known that'I, OGTAVE onoen'aeje citizen of the Republic of France, and resident of Alais, France, have invented a new and useful Improvement in Presses for Ag glomerating Combustible Briquets, which improvement is fully set forth in the following specification.

The present invention has for its object a press to agglomerate combustible briquets.

This press is illustrated, by way of example, in the accompanying drawings, in which Figure l is a front elevation. Fig. 2 is a longitudinal section. Fig. 3 is a plan view. Fig. 4 is a horizontal section.

This press comprises a double hydraulic press A (Fig. 1) with a spring safety valve A. Two vertical frames B are bolted on the press pot and serve as a bearing for the motive crank shaft Q. Besides these two frames are provided two others X, also bolted to the press pot and'which are solidly braced by a cast iron piece receiving the axis of articulation of the lower lever H. A platform D is fastened on the two guide frames B and to the two lateral frames X. Said platform receives and supports a celled plate F arranged in such a manner that it can have no movement save that of rotation around its center. The press also comprises an upper lever G with the support E for its axis of articulation, and the lower lever H, the axis of articulation of which is supaorted, as already mentioned, by the frame X. Two molding pistons I, J, are carried by the levers G and H. The lifting (or unmolding) piston, K is arranged, as represented in Fig. 2, at the extremity of the machine and is operated by a special driv-.

ing-gear which will be hereinafter described. The hydraulic pistons are two in number;

.the motive hydraulic piston M which transmits the motion of the motive shaft Q by means of the rod L, and piston N which transmits the motion to the levers G H. A dog 0 turns the celled plate F one division ateach operation. This dog is operated by the motive shaft Q by means of a rod 0, The apparatus also comprises the return balances of the hydraulic pistons and a motive gear wheel.

There will now be described in detail the characteristic arrangements of the press forming the object of the invention, and

above all that which has particular relation to the return levers of the hydraulic pistons.

The shaft a bearing the return lovers 6 turns in two sockets cast with the frames B of the crank shaft; these sockets are drilled at the same time by means of a special mounting; the trueness and the parellelism of the shaft are thus obtained in a perfect manner. Each of the two levers b is jointed at one of its extremities to the axis of the sliding block M of the motive rod L by means of a small connecting rod 0. The other extremity is supported 011 a block of hardened steel carried by the rod of piston N. The return movement is produced thus in a very simple manner, all the parts are visible and easily accessible.

Means arealso provided to assure the disengagement of the lower molding piston from-the cell a. little in advance of the commencement of the rotation of the plate, which presents the advantage of attenuating to a large extent the shock and the very "noticeable noise by reason of the size of the masses in motion. To this end, the head of the lower lever H is jointed to the hydraulic piston N and the lower piston J is carried free on this lever. At the lower part of the guide 9 of the piston J are arranged two blocks 72., of hardened steel easily dismounted and serving as a rest for the lower piston when it-has disengaged the cell sufficiently.- Two small return levers n keyed on the same shaft 0 are connected by a rod 7 and a crank gto the double lever Z, one extremity of which can be operated by the pin ,t" of the crank m; the pin bears a .roller of hardened steel and the wearing part Patented Aug. 31, 1909.

partwith a key of hardened steel easily dis mounted and on which are supported the two small return levers n (see Fig. 4).

From the preceding it will be seen that as, on the one hand, the lower lever and the hydraulic piston N are solidly jointed, and as, on the other hand, the lower piston is not jointed to the same lever, it follows that the return movement has only to assure the descent of the lower piston alone, and as the weight of this piece does not exceed 200 kilos, it results therefrom that the shock and the noise are attenuated to such an extent that they can be considered as suppresseda;

The ejector K is operated by an eccentric-- with a cam u keyed to a horizontal shaft '0 receiving its motion" from the-shaft of-the machine by suitable means.

The .carn. u iscalculated to produce .sucs cessively the following movements: 1st, rapid coming into contact of the ejector with. theagglomerated briquet; 2nd, very slow and progressive ejecting; 3rd, disengagement of the ejector.

An arrangement for removing the briquet (Fig. 2) consists of a scraper 00 open onlone side. and operated by the shaft 1) and produces, due to a system of levers and rods properly. arranged, the following movements :1st. Removal of the ejected briquet. 2nd. Rapid return to the rear. of the briquet remover.

The general operation of the machine.-

downwardly soas to produce the, molding and the ejecting, and the second to the course of the same shaft upwardly, which causes the disengagement of the two molding pistons I, J and of the ejecting piston K,' 'and "sets. up the rotation of the celled plate F by one division, At each turn which-the crank :makes, the dog 0 causes therotation of the plate F, one division, that is to' say, one cell; B'y' this-thefullcells areisuccessively. presented between the two molding pistons. I,-J .and it is'there that the agglomeration is effected. After this operation, the plate conveys the finished brick to the ejecting piston which'removes it from the mold. .This briquet is seized by the scraper a" which causes it to. fa-ll upon, the endless conveying canvasZ." The downward, movementuof the crank shaft Q causes the hydraulicpiston M to sink in the press pot A'and forces the seco'nd piston Nupwardly'. In this movementythe piston Nfraises. the extremities of. the-two levers G','H." The two fixed supportingpoints of these two levers being on opposite .sides .of the two-molding pistons, I, 'J, the latterhave movements incontrary directions, that is to say," the upper molding pistonI descends while the lower molding-piston J ascends. enetrate at the same time into the cell% d censequently give a double compres sion. It should be added that by this same operation, the ejectingpiston rises in a cell and ejects--one of the briquets previously agglomerated. 1 When the motive hydraulic piston M accomplishes its upward stroke, thesecond piston Nis aided in its descending movement by the return levers b. This movement causes the extremities of the levers G, H and the-lower molding piston J to descend while the upper molding piston I ascends; The ejector K descends and finally allthe pistons are disengaged from the cells. Then the motion of the dog 0 enters into play and makes the plate F turn one division, and when the crank shaft Q is as. high as its deadpoint, another cell filled with the mixture to be agglomerated to receive the compression.

Claims.
